UBUNTU-CVE-2026-33984

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in resizevbarentry in libfreerdp/codec/clear.c, vBarEntry-size is updated to vBarEntry-count before the winpralignedrecalloc call. If realloc fails, size is inflated while pixels still points to the old,...

UBUNTU-CVE-2026-33977

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, a malicious RDP server can crash the FreeRDP client by sending audio data in IMA ADPCM format with an invalid initial step index value = 89. The unvalidated step index is read directly from the network and...

CVE-2026-33985 FreeRDP: ClearCodec Glyph Cache Count Desync - Heap OOB Read

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, pixel data from adjacent heap memory is rendered to screen, potentially leaking sensitive data to the attacker. This issue has been patched in version 3.24.2...

CVE-2026-33985

FreeRDP prior to version 3.24.2 is affected by a heap-based information disclosure (heap memory read) in pixel data handling, leading to potential leakage of sensitive data. The issue is patched in 3.24.2; upgrading to 3.24.2 or later is the recommended mitigation. No exploitation details are pro...
